ADJUSTABLE FOOT-GEAR FOR WINDMILLS.

SPECIFICATION forming part of Letters Patent N 0. 730,524, dated June 9,1903.

Application filed June 24, 1902.

To all whom it may concern.- Be it known that I, JOHN DONALD DOWNIE,windmill expert, of the villageof Avonmore, in the county of Stormont,inthe Province of Ontario, Canada, have invented certain new andusefullmprovements in Adjustable Foot- Gear for Windmills, of which thefollowing is a specification.

My invent-ion relates to improvements in foot-gear for windmills; andthe Object of the invention is to devise a foOt-gearfor this class ofmill which may be located at any desired position On the barn-floor Orany suitable outhouse or supporting-frame and which will ac :5 oommodateitself to any position of machine or any one of several which it isdesired to drive; and it consists, essentially, of a mast or standard,suitable bearings secured to the same, a vertical shaft journaled insuch bearings, a swinging bracket swung on the vertical shaft, ahorizontal shaft journaled therein and in a cup formed on a sleevethrough which the vertical shaft extends, abevel-gear being provided onthe horizontalshaft and'a bevel-gear on the vertical shaft, with whichthe former meshes, and aquad rant being provided whereby the position ofthe swinging bracket may be adjusted so as to hold the horizontal shaftin any position to which it may be swung, the parts being arranged andconstructed in detail, as hereinafter more particularly explained.

Figure l is a perspective view of my improved fOot-gear. Fig. 2 is adetail showing the form of quadrant and of the bracket.

'In the drawings like letters of reference indicate corresponding partsin each figure.

A is the mast, and B and G are the upper and lower bearings, the lowerbearing having 40 formed therewith a quadrant O,provided with a seriesof holes 0. The quadrant O is provided with gripping-lips 0', whereby itis held from vertical displacement on the mast. Both bearings 13 and Gare secured to the mast by suitable bolts.

D is a swinging bracket,through bosses on the ends of which the verticalshaft E extends, such vertical shaft also necessarily extending throughthe bearings B and 0.

Serial No. 113,028. (No model.)

D is a sleeve which is attached to or forms 59 part of the bracket D andis provided witha cup-shaped bearing or recess d.

d is a lug attached to or forming part of the bracket'D and extendinglaterally from the same Over the quadrant O.

F is a bolt extending through a hole 0 in the quadrant C and through ahole in the lug 61 the bolt being securely held in position by a nut.

' Gr is a horizontal shaft which is journaled in the bearing (1 formingpart of the bracket D, and in the cup-bearing cl.

H is a driving-pulley.

I is a bevel-pinion on the vertical or drive shaft, which meshes withthe bevel-pinion J on the horizontal shaft.

It will now be seen that by removing the bolt the swinging bracket, andconsequently the driving-pulley H, may be swung into any positionnecessary, this of course depending on the position in which the machineto be driven is placed and which is most convenient for such machine.The bolt F may then be in sorted and the nut placed thereon, andconsequently the horizontal shaft G and the pulley H held in the properposition necessary for driving the machine to whichit is intended toapply the power.

What I claim as my invention isl. The combination with the Inastandbearings and the vertical shaft journaled therein, 'Of a bracket havingarms pivoted directly to said verticalsh'aft, a horizontal shaftjournaled in the intermediate portion of the bracket and drivingconnections between said vertical and horizontal shafts, substantiallyas described.

2. The combination with the mast and bearings and vertical shaft, of theswinging bracket, the horizontal shaft and bearings therefor on theswinging bracket and'a suitable drive from the vertical shaft to thehorizontal shaft, a quadrant secured to the mast and means on theswinging bracket for engaging such quadrant at any desired point, so asto hold the horizontal shaft in any position to which it may be adjustedas and for the purpose specified.

3. The combination with the mast and the bearings and vertical shaft, ofthe swinging bracket swung on the vertical shaft and having the lowerend provided with an upwardlyextending sleeve having a cup-shapedbearing extending laterally from same, the horizontal shaft journaled inthe bearing on the outer end of the bracket and in the cupshaped bearingand means for holding the swinging bracket in any position to which itmay be swung as and for the purpose specified.

4. The combination with the bearingssuitably supported and the verticalshaft suitably journaled therein and the quadrant provided JOHN DONALDDOWNIE.
